To all whom may concern: I

Be it known that I, 'FRANK-MGOSKER, a'

citizen of the .United States, residing at Turo'n, in the county of Reno and-.- State of Kansas, have invented certain new and'use+ ful Improvements in Thre'shingMachines,

of which the following is a specification.

My invention relates to' new and useful improvements in threshing machines and particularlyto the two cylinder type ofma- .chines. I v

The object of my invention is to provide a threshing machine with two cylinders, one

of said cylinders being of a smaller diameter than the other and -arranged in the rear of Furthermore, the object of invention I 'is to provide a two cylinder machine having.

the concave arranged beneath the cylinder l and a beater arrangedbetween the cylinder in order that the straw after pass1ng be- "low the first cylinder is delivered to the sec- 0nd cylinder by thebeater, thereby insuring the removal of'all the grain from the straw.

Another object of my invention is to provide an improved means for carrying the heads which have not been, thoroughly sepa-. rated from the grain, after passing'through the machine up and forward by means of an endless elevator and deliver them immedi-' ately in front of the several cylinders and in the rear ofthe first beater.

With the above and'other obj ects in vie w the invention consists ingeneral' of a wheel supported frame whereon are mounted a series of cylinders, certain cconcaves, novel means. for elevating the unthreshed straw and re-working the'same together with certain shakers and sieves having an improved eccentric means for imparting reciprocating motionthereto.

Finally, the object 'of' the invention is to provide a threshing machine of the foregowherein like characters denote corresponding parts in the several-mews and n wh ch, 1 is a slde elevation of .my 1111- Figure the invention in detail refs."- had to the accompanying proved threshing machine,,Fig. -2 is a'longitudinal vertical section -therethrough, Fig.

my im roved threshingmachi-ne and is of any desired. constructionsuitable for the mounting'of the parts ofthe machine and which support the-frame and by which the machine may be readily and easilymoved to any location desired. I mount "on'- the side of the frame an elevator casing 4"which is suitably supported by theV-shaped bracket '5. The casing extends from the lower rear end of the frame" in a slanting directiontoward the front of the machine'where it tgminates in a casing 6 extending appro 1 '2 and 3 are thezf-ront and rear truck wheels mately to the center of the machine where it has an openlng extending into the interior of the machine. I provide my improved machine with two cylinders 7 and 8having the ordinary spikes secured to bars. The cylinder 7 being of a greater diameter than the cylinderS is located in the front of the machine and the cylinder? i being of a smaller diameter is located in the rear of the first mentioned cylinder. Beneath each cyllnder I provide a series of bars 9 on which I suitably secure teeth or spikes ,7

10. The general plan of constructing the. .concaves is to make them in one solid piece withfthespike's threaded therein, but I arrange-them a. series of barswhich are suitably secured beneath the cylinders and I end of the -rod' I pivotally secure to the' In front of the cylinders '8 Iprovi'de are a predetermined distance apart so the end of the machine a casing 13 which extends entirely across the machine and is provided with an opening: extending itsLentire In this casing I secure .a screw con eyer-H and attached to one end I secure a small pulley wheelI 15. In the casing 6 I also. provide a screw conveyer 1'6 having a .sm'all pulley wheel 17, on -'the "extreme of its shaft within'the casing 4 I arrange an end less 'belt 18 having transverse bars 19,011 which the unthreshe'd'grainheads are deposited by the. screw conveyer- 14, and can ried' up and deposited into the"tcasing 6 where they, aretransiferred to the interior of the machine by the screw conveyer 16 immediately in front of; the rear cylinder 7 and as theunthreshed, heads :fall 'into the machine they strike the beater 12 which throws them with considerable force; a'gainst the cylinder 7 which carries them beneath and-rethreshes theI'n, thus insuring com-l plete separating of the grain from the straw.

Inthe rear of-the 'cylindersI attach by the hangers 20, on one side, but both sides are of similar arrangement, a shaker comprising-two sections 21 and 22 hingedvtogether at 23. By this construction I provide a shaker in which the. rear portion can be adjusted to prevent the ,grain, from being driven out with the straw; "The lishbacks'25'are' arranged in rows running longitudinally of the shaker and are suitably secured to the'transverse bars ofythe shaker. In order that the shaker nay have a reciprocating motion I provide an eccentric 26 suitably secured on' a shaft which is rotated by the pulley wheel27. An eccentric strap 29 has'a rod 30 suitably secured at 'onevend thereto and the opposite shaker frame or siderailat 31;

To receive thegrainthat falls through the sha'ker and also that which falls between the bars 9,' I providea .grain pan 11 which extends the entire length of the machine and is provided Withanupturned porboard 39' suitably of the cleaning device shown in the drawingon-ly I grain and causes it to drop through the opening. The outer slanting edge diverts the'unthreshed' heads into the screw conveyer where they are again taken I up and deposited-in vthe machine as hereinbefore described- I provide a series of sieves 36 and 37-suitably secured-in a frame which is given a reciprocating motion through the eccentric heretofore referred to. I also provide a fan 38 located below and" in front of the sieves 36 and 37 and between the. fan and sieves I -'provide a wind regulating v hinged at its upper edges and provided with means for adjusting the height of the same.

I provide an ordinary srew 'coni'e'yer 40 which conveys the grain to'the exterior'of the machine when it may be secured in the ordinary measure or sack.

It willbe noted that I provide the cylin- Inthe lower rear end der.with small pulleys ll and -12 over which ally employed in threshii ig machine s. 7 It s behevedthat the construction and' operation of my improved threshmg machine may be understood from. the above dos'cription.

Having thus fully described. my said invention, What IcIaini as new and desire to secure by'Letters Patent is: v y

In a threshing machine, a frame, a. pair of cylindersof different diameters arranged transversa'lly on said frame in different horicylinders; suitably secured oh said frame, a return grain spout having its exit above-and in front of said rear cylinder; a heater trans in presence of two witnesses.
